@Softwaretom007 Thank you very much! |
Add Drawing Unconnected lines Add fill & draw rectangle single call Add DrawStringLayout call
|
Added more functionality (string layout, text antialiasing setup, optimized draw & fill rectangle and drawing unconnected lines - from array of points). |

Is this needed in C#? Isn't the uint specifier adequate to ensure the type's size?

Hi,
I don't understand your question.
This is enum for setup only possible antialias modes.
Value 0xFFFFFFFF is indeed maximum value for uint, but is correct value for "FORCE_DWORD" mode.

I assumed (perhaps incorrectly) this enum member was ported from a native library where it was forcing the compiler to treat the enum as being 32 bits rather than something smaller. If that's the case then it's not needed in C#, where the base type of the enum is explicit.
But if this value is for something else then you can ignore my comment.

Okey,
now I understand 😄
There is no additional info for constant:
D2D1_TEXT_ANTIALIAS_MODE_FORCE_DWORD = 0xffffffff
So if this is only for "messing with compiler optimizations" in C/C++, as you say force to be 32bit.
Then yes, this don't belong to C# port.
First I thought that FORCE_DWORD is some "super" mode.

Other enums in this file have names like DWriteFontWeight, with members like FontWeightThin (ie. not all-caps with underscores).

Fixed in next commit 6470087. Thanks

Very appreciate it! |
Add D2DSolidColorTextBrush object and interface + extend MeasureText with D2DFontFormat fontFormat and D2DTextLayout textLayout + update Sample/MeasureAndDrawString + update FPS meter algorithm
MeasureAndDrawString yield 2x performance gain using cached SolidColorTextBrush and FontFormat.
